There are lot of activities are going on in scientific field and inventions. Recently scientist has developed a smallest laser whose wave length is ten times smaller than the wave length of light. They have given its name as ‘Spacer”. The Spacer will enable to develop a new generation of microelectronics chip which will be thousand times faster in processing various data information. Thus very soon we can expect to get more faster computers, which will replace present generation of super computers. At present the experiment is going on in laboratory. Scientists are working overnight to develop it in a commercially available form.
